SPECIFICATION forming part of Letters Patent No. 710,795, dated (dctober7, 1902.

Serial No. 112,954. (No model.)

To (1J5 whmn it may concern/.-

Be it known that I, FRED Mosnn, a citize of the United States, residingat Auburn, in

the county of Cayuga and State of New York; 5 have invented certain newand useful 1mprovementsin Nut-Locks; and I do hereby declare thefollowing to be afull, clear, and eX- act description of the invention,such as will enable others skilled in the art to which it to appertainsto make and use the same.

This invention relates to that class of nutlocks in which a locking-wireconnected with the nut and having an arm or portion adapted to engagethe slottedend of thebolt serves as the medium forlocking the nut to thebolt;

and the invention has for its object to provide a simple and convenientn ut-lock of the character referred to..

In carrying the invention. into effect the bolt is provided at its endor face with one or more transverse slits or slots, and the nut isprovided at its outer face with an annular groove or recess surroundinga flange or lip having one or more notches, and the lockingwire has acircular body portion adapted to lie in the said annular groove orrecess and having an arm bent inward to extend diametrically to the nutand bolt, so as to en-.

gage a recess in the nut, and a transverseslit in the end of the bolt tolock-the two parts together.

Referring to the drawings,Figure 1 is a side view of a bolt and nut withmy improved Referring to the drawings, A denotes a bolt which may be ofany suitable construction 5 and which has a threaded portion on whichfits a nut 13.

end withone or more tran'sverse slits or slots to, and the nut B is cutaway at its outerface to form a reduced portion which affords an 5 oannular recess or groove 12, adapted to receive a locking-wire 0, havinga circular body portion received in the said groove or recess in'cidentally loosened-or displaced by any jar- .ring towhich it may besubjected.

The belt A is provided at its.

the bolt and having also an inwardly-extending arm a, which is disposeddiametrically to the uut'and bolt, so as to engage any one of a seriesof notches 5 formed in the outer face of the nut and enter a transverserecess hint-he outer end or face of the bolt. The extreme end of thewire forming the arm 0 is preferably bent back upon itself to form aloop or fingerpiece which affords a convenient means for removing thelocking-wire from the recesses ornotches in the outer face of the nutand the end of the bolt when it is desired to unlock the nut.

In the form of my invention shown in Figs. 1 and 2 the locking-wire isretained in its annular groove or recessin the outer face of the bolt byits own resilience, as its circular body is of such SlZQflS to snuglyembrace the notched flange afforded by the groove or recess in which thewire lies, while in the form of my invention shown in Figs. 5 and 6 oneend a of the locking-wire is received in a notch b in the edge of thebolt, so as to hold the locking-wire in place.

From the foregoing it will be apparent that when the nut has beenscrewed onto the bolt 'to any desired position and the locking-wire isthenapplied thereto, with its inwardly-extending arm in engagement withan'otch in the faceof the nut and a slit or groove in the outer end ofthe bolt, the nut will be securely locked in place, so that it cannotbecome ac- Havingthus described my invention, 1 claim and desire tosecure by Letters Patent 1.
